Gas chromatography using small TBAB semi-clathrate hydrate particles is examined as a new practical application of clathrate hydrates. To clarify the elution characteristic, some gases with different molecular sizes and polarities such as methane, fluorocarbons (CH_2F_2, CHF_3) and noble gases (Ne, Ar, Kr, Xe) are injected into the apparatus. As a result, retention times (RT) of noble gases (Ne, Ar, Kr, Xe) are varied according to the molecular size of those. It suggests that TBAB hydrate stationary phase works as a molecular sieve on the chromatography. Polarity of each gas dominantly affects RT of this chromatography in spite of the molecular size effects.
